ITS CALM Mobile Wireless Broadband applications using Communications in accordance with IEEE 802.20 (ISO 29283:2011, IDT)
This International Standard specifies the options appropriate for CALM using mobile wireless broadband (MWB) techniques conforming to the IEEE 802.20 air interface and protocol specification recommended by ITU-R M.1801 and specifies the management interface requirements.
CALM links are required for quasi-continuous, prolonged and short duration communications between vehicles and the roadside, between vehicles, and between mobile equipment and fixed infrastructure points, over medium and long ranges.
Wherever practicable, this International Standard has been developed by reference to suitable extant standards, adopted by selection. Required regional variations are provided.
Application specific upper layers are not included in this International Standard, but will be driven by application standards.
